Optical Receptacle Segmented Support for Wire Bonding Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical modules have limited space for wire bonding and other components due to direct adhesion of the optical socket to the board, restricting design freedom and component placement.
Innovation Solution
An optical receptacle with a supporting member is used, allowing the optical-receptacle main body to be spaced apart from the board, featuring first and second optical surfaces for light transmission and reception, and fitting portions for secure attachment, enabling greater design flexibility and component placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the optical socket is directly adhered to the board, then the optical module structure is simple, but the region for wire bonding and other components is limited
Solution Approach 1:
The optical socket is divided into two separate parts: the optical-receptacle main body and the supporting member. The supporting member is fixed to the board while the optical-receptacle main body is mounted on the supporting member, creating a segmented structure that resolves the contradiction between structural simplicity and design flexibility.
Solution Approach 2:
The invention introduces a vertical dimension by stacking the optical-receptacle main body on top of the supporting member, which is itself mounted on the board. This three-layer vertical arrangement frees up the horizontal board surface for wire bonding and other components, solving the space limitation problem.
2Ease of manufacture
If the optical socket is directly adhered to the board, then the fixation process is simple, but the space for wire bonding and other optical/electronic components is restricted
Solution Approach 1:
By segmenting the optical socket into a supporting member and an optical-receptacle main body, the invention enables the supporting member to serve as the fixation interface to the board, while the optical-receptacle main body occupies vertical space rather than horizontal board area, thus preserving valuable board real estate for other components.
Solution Approach 2:
The invention transitions from a two-dimensional board surface arrangement to a three-dimensional vertical stacking configuration. The supporting member is fixed to the board in one layer, while the optical-receptacle main body is mounted above it in a second layer, effectively utilizing vertical space and freeing up horizontal area for wire bonding and other components.

AI summary
The optical receptacle of the present invention comprises an optical receptacle body and a support member. The optical receptacle body comprises: a first optical surface upon which is incident light transmitted from the photoelectric conversion element; a second optical surface that emits light transmitted from the photoelectric conversion element to the light transmission medium. The support member comprises a support member body that includes a mounting surface for mounting on a substrate, and a second mating part that mates with the first mating part and that is positioned at a position on the inside of the support member body at a position corresponding to the first mating part. The optical receptacle is positioned on the support member side of the mounting surface.
